To all whom 15 may concern Ee it known that 1, HEINRICH DREWELL, a subject of the 'German Emperor, residing at Charlottenburg, Germany, have invented new and useful Improvements in Automatic Line-Casting Machines, of which the following is a specification. v

My invention relates to automatic matrixsetting and line-casting machines operated by means of perforated bands. lts Special `object is to adapt matrix-setting and linecasting machines of the kind as described, for instance, in theU. S. A. patent specifications 436,531, 436,532 and 551,000, for operacan be produced by manipulating any. ordinary typewriting machine combined with a pertorating device. Hereby the casting device in the ldergenthaler Vmachine and also the greater part of the setting apparatusis not altered, though devices for striking the keys with 'the aid of electromagnets are fitted underneath the llzeydevers, and these electromagnets are energized in correspondence to the perforations 'of the band. rfhis part of the device has already been described in my U. S. A. Patents E56-1,519 and 915,74t8. The striking oit' the lreys causes delivering of matrices, as described in the before mentioned speciiications. The lines are justified by means of the well lmown wedgeshaped an justiers. ln such lines however, in which he enlarging possibilities o1 these gust-15ers do not sullice, blank-matrices are employed and inserted besides the wedge-shaped justiiiers during the setting ot' thelinc. The method employed to obtain this by means of perforated bands, has also been described in detail in my U. S. A. Fatent 954,023.

The proceeding of the band is stopped or delayed for a moment when one of the wedge-shaped jusiiiiers is being set, on account of the greater length of the latter causing trouble in the regular falling and gathering of the-comparatively shorter and therefore quichermmlatrices.

ritter the completion oa line the assembling elevator is raised by means of a spring, so that 'the line may be transieircdto casting` position. Between the setting of the last matrix o1 a line and the raising of the assembl ing elevator however, 'a short pause is inserted automa ally, whicl'z assures that Specification of Letters Patent.

39,'the shaft 36, the-band feeding roll 5 and the perforated band 1 itself then remain stationary for' a--short time. The coils 119 of the electromagnet 118 are in series or in parallelwithj the coils of an electromagnet of the keyboard G controlling the delivering of tlie Wedge-shaped justifiers. .Both these electromagnets are energized when the Wordsepa'rating symbol 306 of the perforated band actuates on the corresponding levers 22. When this occurs a Wedge-shaped justilier is delivered the movement of the perforated band-being simultaneously interrupted for a moment and its action delayed, 4thus leaving a suliicient time to the Wedge-shaped i the perforated band in front of the first character selecting symbol of a line during the composition of this line besides each wedge-shaped justifier a blank matrix must be delivered into the assembling elevator. This is performed as follows: The ratchet- Wheel 106being provided With two teeth 112 and tivo teeth 113 each attraction of the armature 117 causes half a revolution of the bevel Wheel 104, ratchet-Wheel 106 and the cam 107. This half revolution consists of two steps which are separated from each other by a tooth 113 abutting against the pavvl 111. During the first of these steps the contact spring 122 leaves the contact screw 124. During the second step one of the projections 10S or 109 on the ca-m 107 actuates on the contact spi-ing 123'and presses it against the spring 125, thereby closing an electric circuit, which contains besides the springs 123 and 125 the coil of a key-operating electromagnet and a band-controlled switch. The latter is operated by two electromagnets one of which is energized when the justifying symbol actuates on corresyjionding levers 22 of the apparatus as hereafter described more particularly. The switch is then thrown into its operative position and 'remains therein during the assembling of the line, until the symbol 308 placed on the band behind the last character selectingsymbol of the line becomes operative and throws the switch into its inoperative position. As long as the switch is in its operative position each contact between the springs 123 and 125 causes the key-controlling electroniagnet the coil of which lies in the same circuit to become energized and to strike its key, which delivers ,ose

a suitable blank matrix into the assembling elevator, thus completing the |ust1lication of the line in question. The shaft 18 is driven by means of a pulley 130, 'which is arranged behind the case L and rotates loosely on shaft a8. The pulley may be driven by any continually rotating shaft of the matri7 -setting apparatus.

In order to obtain uniformity between the feed of the perforated band and the operation of the vkey-board mechanism, l prefer to drive the pulley 130 with the aid of the shaft of one of Well known rubber rolls 2 and 9).the forked end 137 of Which carries two pins 13b' and engages therewith in a circular groove on Athe sleeve 1311, which is l connected to the crown wheel 133. The lever 137, 138 is pivoted on the rear side of the case L and its arm 138 rests against a cani 139 Which is secured on a shaft 1110 and carries tivo'projections 112 andv 1&3, the latter of which acts on the end of the lever arm 138. A suitable spring (which is not shown in the drawings) tends to brine'. the crown- Wheel 133 in engagement with the crown- Wheel 132 thereby pressing the lever arm 138 against the cam 139. The `shaft 140 carries on its other'end that is on the frontside of the'case L a crank lell. The projec- These pins forked end 146 carries pins 147.

engage in a groove 143 of a. hush or sleeve 1-19, which forms a part of the Well known coupling device controlling the (having or the transferring belt E of the Mergenthaler l line casting machine. A pulley 152 is loosely mounted on the continually rotating shaft 151 and is provided with a hub having` a recess 157. Projections 150 of the sleeve 1119 which paritaires in the continuous rotation of the shaft 151 but is axially displaceable on the latter engage this recess thereby transmitting the rotation of the shaft 151 to the pulley 152. The latter drives a suitable pulley on the shaft 155 (Fig. 9) on which a pulley 156 is secured. The latter pulley drives the transferring belt E.

The shaft 1110 of the handle 141 carries a contact roll 16() consisting of an electrically insulating material, in which a metal piece 161 (Figs. 2, 3 and el) is dove-tailed. Three springs or brushes 162, 103 and 134 slide on the roll and are, in the operative position of the roll, electrically connected n lino of matrices to casting position( The piiojcctioiis MZ and H3 of thc cam 139 and the mctnvl piece lol. ci the contact roll 166 :t1-.c connected in such way that thc main part oin the, apparatus one iittei' am' othci" become; opci'utivc.

After the line lhas -been filled up with blanks the spring 198 must ce Withdrawn from the contact screw 200 and the nieve nient ofthe Contact roll 183 must he stopped. For this purpose the slide 206 (Figs. 1 and 9) which carries the sse-called line resistant.v

205 isprovided with a stop 207 which hy a. clamping screw 208 can he secured on the slide 206 according to the length or the lines to he composed. To the slide 206 there is attached :i cord 212, which is guided by a roller 213 to a cani 214-. A spiral spring 216 within acaso 215 tends to rotate 'the Cain 214 and to Wind the cord 212 on the cain 214. The latter is so shaped that the tension of the spring' 216 which acts on the slide 200 is somewhat diminished when the slide 205 advances. As the'resistance caused hv the 'friction of the already assembled matrices inc eases :recording to the increase or length of ie line the w icl-e resistance against the advancing of the matrices in the assembling elevator rein-i nearly unaltered during composition of a li @n the upper end or the stop L0? attached a neck screw 209, which slides in slot 210 en the one end of a drew-rod 211. '1" he other end of this drawis operativel;1 cennectedto a. lever on the rearside of the 'Ease L. An angle lever 218, 21I is pivoted on the le it end (Fig. 9) of the draw-rod 211 and lies in its rest position with its vertical arm 218 on a stop pin 220 secured in the mein 'freine oli the line casting machine. el spring tends to move the lever 21S, 219 and the draw-rod 211 to the right (Fig. l1) until the lever 225 ebuts against a stop 224i arranged on the rear side of the case L. Baring the composition of a line the slide 206 is moved to the left and when the line is nearly completed taires with it the draw-rod 211. Owing to the tension of the spring'l the upper end ci the. lever arm 218 rests on the stop 220 whereby the angle lever 218, 219 turns around its pivot. until the lever arni 219 abut-s against the he: d the neck-screw 209. luring the fun ther inevenient of the draw-rod 211 the lever 218 leaves the stop 220 and the necl: screw 209 is clem' hettveen the arm. 219 and the bottoni oi the slot 210. Thus the d sw-rol 211 is so Alined to the slide 206 that stepwise movement ci! the'latter does not advance the rod 211 nacre. than the slide 20s.'.

The lever 225, to which the rod 211 is on eratively ccnnectedQis secured on :in axle 226, which passes tiro-ugh the rear wall of cese L and carries on the inside a two armed 22'?, 228 and e pawl 8 and 0'). .ihe l.

The electric current, which operates the blank delivering keys is here interrupted and the deliver-ing ot' blank matrices ceases. Besides the three-armed le ver 235,236, 237 an angle lever 240, 211 is rotatable around the neck'serew and is by a spring 242 pressed against a. stop pin 213 on the arm 235. This angle lever 240, 241 and the two-armed lever 245, 246 in this ease Serve to stop the movementot the contact roll 183 and to cause the assembling ele vator to be lifted.

The lever 245, 246 bears an antifriction roll 250 on its left end and an adjusting -screw 252 on the right end (Fig. 8). The `roll 256 rests on the cam 72 and the screw 252 on the arm 1,93 ofthe. angle lever 192,

193. A neck-screw 248 guides the lever 245, 246 by means of a slot 247. The lever, which is also provided with a hook 249 adapted to engage with the pawl 240, can be rocked by the projection 251 of the cam 72. As long as the pawl 240 does not engage with the hook 249, the lever 245, 246 when lifted on its left end by the projection 251 turns around the supporting point of the adjusting screw 252 without de ressing the lever arm 192. But when the liook 240 engages the hook 249 which occurs when the pawl 233 releasesthe three-armed lever 235, 236,037, the rising of the roll 250 on the lever Q4-5, 246 causes a depression of the adjusting screw and the lever arm 193 brings the arm 192 behind the pawl 191, which. again locks the angle lever 192, 193 in its inoperative position. Also the rod 1954 is brought to its inoperative position thereby allowing the spring S3 to engage the dog 82 into the recess of the rod 79. Daring.

.the 'following revolution of the disk 69 and cams 71 and 72 the projection 77 of the former cam depresses the lever 6l and simnltaneonsly the rod 7 9. This restores the lever 78, the shaft 66, and lever 68 to their rest position, whereby the latter brings the clutching pawl ont ot' engagement with the crown wheel 70 and thus stops the movement ot disl; 69 contact roll 16?, and cams 71 and 72. The depression ot the rod 79 also causes the spring 96 to contact with the spring 95 in order to release tl i assembling elevator and to allow the assembled line of matrices tobe transferred to casting position.

To lift the assen'lbling elevator i'roni its assembling position to its line transferring position the device shown in detail. in liigs. 12, 13 and 14, is employed: On. the main frame B ol' the machine and below the assembling elevator :L bearing frame 26S (Fig. 12) is secured in a suitable manner. Mount- A spring he lever 263 is provided with hoolt or pawl 261, which engages a nose 265 on thc lever 266. The latter ijs rigidly seem-ed on a` shaft 267 which is rotatably mounted in the bearing 'frame (.)n the same shalt isattachcd a further lever 269 in the forked, end of which a rod 271. is guided by a pin 276 which passes through a slot 272 of said rod and is secured .in the forked end of the lever 26E). The upper end of the latter is pivot ally attached to the assembling elevator l?. The pin 27 0 carries a. cylinder 273 in which a piston 27 4 pivoted to the bottom end o't' The cylinder 273 andvator F when the latternlrops down to its lower position. If the lever arm 269 swings upward the assembling elevator l*1 is lifted by means of the rod 271; the lower end of the latter swinging to the right in Fig. 12 and followingI the curved way of the lever arm 269.

With the lever arm 266 there is connected the one end of a sleeve or bush 27 5 which on its other end is provided with e reoess 276. In this engages a projection 277 of the hab 27 8 of a lever 279 to which the bottoni end of a rod 281 is j'iivoted by a. pin` 280. The top end ol." this rod operatively connected to the end of a lever 282 which is rigidly fastened on the shaft 2&5 (Figs. 1, 12, 13). The latter is the so-ealled linetransferring shaft ot' the l\[ergenthaler li neA casting' machine which serves to operate the line Atransferring carriage M by means of the lever 261. How these latter parte are operated is well known from the betere mentioned patent sjjiecilieations and needs not to be described here.

A\ronnd the sleeve a. torsion-sining 266 (Fig. lil) is wound which engages on the one end a suitable hole or recess ol the sleeve 273 and on. the other a, similar hole or recess ot the hnb 278 of the lever 279.

.ln its rest position this spring is wound np suitable spring which is not shown on the drawings and depresses by means of the lever the rod 281, thereby transmitting its rotation in an opposite direction to the lever arm 279 and its hub 278 and further by means of the projection 277 to the sleeve 275 and the shaft 267. The coperation of the assembler-lifting spring 286 and the means for winding it up depends upon the projection 277 and its position within the recess 276. In the rest position of ,the machine, z'. e. when the assembling elevator F is in its lower position and the line transferring carriage M in the position shown in Fig. 1, the face 277a of the projection -277 lies close to the face 276 of the recess 276.

Now if the assembling elevator F is lifted toits upper position, the sleeve 275 is turned in the direction of the arrow 275L (Fig. 18) and as the hub 278 remains at rest the face 276b of the recess 276 is placed close to the 4face 277b of the projectie`- 277. if, in this tion. the tension of the springl 286 remaining 'between the faces 276n and 277m.

unaltered. At the end of this rotation the shaft 267 and the sleeve 275 are locked in their positions by the pawl` 26-L catching the nose 265. Now if the line-transferring carriage is restored to its rest position by means of the well known cani on the main cam shaftof the Mergenthaler line-casting machine the hub 278 is rotated in the. direction opposite to that of the arrow 278 in Fig. 19 without transmittingthisrotation'to the sleeve 275 there beingsui'ticient space As only one end of the spring 286 partakes in this latter rotation the tension of the spring 286 is thereby restored to the amount necessary for lifting the assembling elevator F.

During the first part of the first rotation of the shaft 283 and the movement of the line-'transferring carriage toward the casting elevator A the assembling elevator F is in a well known manner held in its upper position by a catch 310 (Fig. l.) which is pivotallv connected to thc rear side of the assembling .elevator and when the latter arrives in its upper position engages into a suitable recess of a rail 311. Then the line of matrices has completely entered the iii-- termediate guide N, the line transferring carriage M disengages the pawl 310 from the rail 311 and the assembling elevator F drops down into its lower or assembling position by its own weight. As the pin 276 slides in the slot 272 the downward movement of the lever arm 269.I which begins together with the movement of the line-transferring carriage el, isy not prevented by the assembling elevator remaining stationary for the time necessary for ti'aiisferring the line of matricesfrom the assembling` elevator F into the guide On the shaft 267 and beside the hub 278 there is rigidly secured a small disk 290 provided with a nose 2917 which normally depresses a lever 292 which is pivoted at 293 against the tension of a spring 300.v A pin or finger 295 secured to the lever 292 by means of an intern'iediato piece 29% made of electrically insulating material normally;T vholds a contact lever 296 against the action of a spring 391 out of contact with a contact screw 297. The lever 292 has projection 298 opposite to which a projection 299 is provided on the hub 278 of .the lever 279. The contact lever 296 controls the energization of the electromagnet 96 (Fig. 7) which serves for rendering the band feedingT device operative when the composition of a new line is to be commenced. lVheii the assembling elevator F leaves its rest position and the shaft 267 is rotated, the nose 291 allows the lever 292 to move until its projection 298 abuts against. the projection 299 of the hub 278. Now when the line-transferring carriage M is released and shaft 283, lever 282, 279 and hub 278 begin to rotate the projection 299 is displaced and allows a further movement of the lever 292 whereby the lever 296 comes into contact with the Contact screw 297 and the clcctroniagnet 99 (Fig. 7) becomes energized. lYhen the assembling elevator returns to its assembling position. the levers 292 and 296 are again depressed by the nose 291 andthe current of the, electromagnet interrupted. This restores as described before the feed mechanism of the perforated band to its operative position and the automatic matrix-setting goes on.
